Hello, Your vehicle system works with Hazard Lamps The BCM (body control module) sends a voltage signal to the FCIM to monitor for a hazard lamp function request. When the hazard flasher switch (a capacitive touch switch) is touched, the voltage signal is routed to ground, indicating a request to activate or deactivate the hazard lamp function. When the BCM receives a request for the hazard lamps, the BCM supplies on/off voltage to all the turn lamps. The timed on/off cycle for the hazard lamps is approximately 80 times per minute regardless of bulb outage. This is what you should do is a complete reset of the system. Disconnect both of the battery cables wait 5 minutes and than touch the cables together. Reconnect them and see if resetting the modules does the trick and let me know.
The vehicle will start run and drive without any flashing theft lights on the dash?
